How can I create a scheduled java application/task?

Hi,
Being a complete newbie to the Java language, I hope I am forgiven if the above is blindingly obvious.
I have a java application which I have developed that when run from the command prompt (java xyz) selects a bunch of records from my database, then creates a text file with the results. Pretty simple stuff.
My question is, how can I automate this process? I would like it to run every night at midnight. Will I have to create a batch file? If so, how? Help!!
Any advice would be much appreciated :)
Thanks, Chris

Scheduling a task is a very Operating System dependent operation. It does not exist in some OS's without some kind of addin. Things of this sort are usually not done exclusively in Java, unless you want to have your application running all the time and simply perform some operation at a specific time (see Timer). Otherwise look on google.com for 'scheduler' and 'windows 98' for example.

How can i create messenger with java tv API on STB

how?
i am interested in xlet communications with java tv.
is it impossible or not?
help all..

You can create a messenger-style application using JavaTV fairly easily. JavaTV supports standard java.net, and so any IP-based connection is pretty easy to do. The hard part of the application will be text input, but people have been using cellphone keypads to send SMS messages for long enough that they're familiar with doing this. This doesn't work well for long messages, where you really need a decent keyboard, but for short SMS-type messages it's acceptable.
The biggest problem that you need to work around is the return channel. Many receivers only have a dial-up connection, ties up the phone line and potentially costs people money if they don't get free local calls. Always-on return channels (e.g. ADSL or cable modem) are still pretty uncommon, so it's something that you nee to think about. Of course, if you do have an always-on connection then this problem just goes away.
This is really one of those cases that's technically do-able, but the infrastructure may not be there to give users a good experience.

Can we Create Setup of java Applications ?

Like VBasic can we create the setup of java Application containing main function. How to do this ?

It's possible the OP is asking about installers. The
last time I seriously used VB (in the 1990s) it came
with a cheapo installer so you didn't have to pay
money for InstallShield.Then perhaps the OP might wish to try something like this?

How can I create a schedule in Java for sending mail from SAP?

Hello;
I am coding a programme in Java which reads data from KM. I wish to schedule a job which sends mail to a list of persons selected from KM. I read the article by Prakash Singh and based my programme on his explanations.
/people/prakash.singh4/blog/2005/04/20/did-you-know-you-can-schedule-jobs-in-portal-using-kms-scheduler-task
My first problem is that I don't know how to send mail in SAP, and how to use Java to send this mail. My second problem is how to develop this "schedule job" function - is it enough to use Prakash Singh's method, or does it need to be changed?
Can anyone help me with these questions?
Thank you very much, R.E.

Hi,
I dont know about the CATS system. But when ur user selects the varaint, he should remove his own id and execute the query. This should display all the variants existing for that program. Then he can select the required variant.
The user can also save this varaint under his own ID
Hope it helps.

               driverClassName="oracle.jdbc.OracleDriver"

              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1"/>
but when i have used this way i got following exception.
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

https://forums.oracle.com/thread/2564233
2. write following line of code apache conf/Server.xml file
<GlobalNamingResources>
    
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"

How can I know the version of Application Server Java Virtual Machine

How can I know the version of Application Server Java Virtual Machine?
Thanks a lot.

Thats easy. Your jdk/jre are located in the App Server home directory. Just run the java command under the jdk directory with the "-version" switch and it will provide you with detailed information about your VM.
For example if you're doing it at command prompt it will be something like
java -versionI hope this will be useful to you.

Is there any spinControl in Java? If not how can i create it. Thanks in adv

I need a controller which will increment and decrement the integer value in the textField. Just like the spin control of printdialogbox of word or netscape. How can I create it?

There is JSpinner in JDK 1.4.
If you are using an earlier version, you will need to create your own.
All you need is a JTextField and two buttons. Attach actionListeners to the buttons, and depending on which button is selected, change the JTextField value.
Hope that helps.

How can I create a simple chat function in a mobile app for iOS and Android

I am wondering how can I create a chat function in my mobile app creating in AIR and Flex. The chat should be similar to the one in WhatsApp.
Do you know some possible solutions?
Thank you in advance!

To enable chat messages, you need a server. The kind of server depends on the application. Do you want to create a chat like application like WhatsApp, where the server pushes messages without an active connection? Or do you have some sort of online game, where chat messages can only be transferred when the client is connected already?
I have an online game where clients are connected to a Java server at all time. From there it is pretty straight forward:
2 textfields:
- 1 line textfield for input messages
- multi-line textfield for chat history. Make sure the textfields autoscrolls to the bottom when the content changes
on enter or button push, send a socket message to the server.
the server broadcasts all messages to all clients that are subscribers of the chat group.
